SPINDLE FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 426,815, dated April29, 1890.

Application filed February 6, 1890. Serial No. 3 39,388. (No model.)

To all whom t may concern.:

Be it known that I, WILLIS C. HOWE, a citizen of the United States, anda resident of Evansville, in the county of Vanderburg and State ofIndiana, have invented certain new and useful Improvements in Spindlesfor Vehicles; and I do hereby declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled inthe art to which it appertainsto make and use the same,reference being had to the accompanying drawings, which form a part ofthis specification, and in which-n Figure l is a longitudinal sectionalview through the axis of my improved spindle. Fig. 2 is a perspectivedetail view of the nut at the outer end of the spindle; and Fig. 3 is aperspective view of the nut-locking bolt, which operates to hold the nutin place.

Like letters of reference denote corresponding parts in all the figures.

This invention relates to spindles for Vehicles of that class in whichthe nut which holds the box upon the spindle proper is locked inposition by means of a bolt working in avthreaded recess or bolt-hole inthe outer end of the axle-spindle; and my improvement consists in thedetailed construction and combination of parts of a vehiclespindle ofthat type, which will be hereinafter more fully described and claimed.

Reference being had to the accompanying drawings, the letter Adesignates the axlespindle proper, which may be provided with a shoulderB, if desired; or it may be made tapering from end to end, according tothe kind of box with which it is intended to be used. The outer end ofthis spindle is reduced and screw-threaded, as shown at C, and thisthreaded extension C is bored through longitudinally and threadedinteriorly, so as to form a threaded bolt-hole D, the screwthreads ofwhich run in reverse direction to the exterior threads. Inother words,if the threads on the outside of the reduced part C run from right toleft, then the threads in the inner bolt-hole D run from left to right,and vice versa. The spindles are always so arranged relative to theaxles and the vehicle supported on the axles that the locking-boltswhich are screwed into it the bolt-holes D will, as the vehicleprogresses, have a tendency or impulse to work into their respectivebolt-holes and thus bind upon the nuts. This is accomplished by makingthe inner threads right-hand on one side of the vehicle and left-hand onthe other.

The locking-bolt (shown at E) has a head F and a conical short neck G,fitting into a conical countersink or recess II in the outer end of thepart C. The outer end of the spindle where. this merges into thethreaded extension C is also turned od to form a short cone I, for thepurpose hereinafter-set forth.

The axle-box (shown at J) is screw-threaded at its inner end to seat anexteriorly-threaded ring K, which holds the lubricating-washers L inplace in the usual manner. The outer end of the box is enlarged, asshown at M, the inner end of this enlargement being beveled, as shown atN, to tit against the corresponding bevel on the axle-nut. The latterconsists, essentially, of three parts, which are, however, integral withone another. These are the outer square or hexagonal part O, adapted toreceive a wrench or Spanner for removing or fastening the nut, anintermediate circular disk P, provided with an inwardly-projectingannular flange Q, and the cylindrical part R, adapted to t within theenlarged outer end M of the box, and having an outer bevel S, bearingagainst the bevel N of the box, and an inner bevel T, similarly bearingagainst the spindle-cone I when the nut is in its proper workingposition. By the peculiar construction of this nut, with its cylindricaland beveled portion R, in conjunction with the spindle-cone I andbox-bevel N, the nut may be so adjusted as to readily take up wear andprevent any longitudinal motion of the box upon the spindle.

The object of the circular disk P, with its ange Q, which, when theparts are in proper juxtaposition to one another, overlaps the outer endof the box, is to prevent dust and dirtfrom entering between the spindleand the box from the outside. l

As stated at the outset of this specification, the nut, after it hasbeen properly adjusted upon the spindle, may be locked in place by meansof the locking-bolt E, by loosening IOO which the nut may readily beadjusted to compensate for Wear, as may be required, in a moment of timeand with absolute etlicieney.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States- The combination, in a spindle forvehicles, of the following elements: the axle-spindle having the outereene or bevel I and reduced screw-threaded extension C, provided with aninner threaded and countersunk bolt-hole, the threads of which run in adirection reverse to the exterior threads, the locking-bolt E, having aconical neck G, adapted to fit into the conical countersink at the outerend of the bolt-hole, the axle-box provided with WILLIS C. HOWE.Witnessesz ROBERT H. EASTBURN, JOSEPH K. CoArEs.
